Question 1

Which of the following is NOT a characteristic of epithelial tissue?

Accepted Answer

It contains abundant blood vessels within the tissue.

Question 2

A patient presents with a rapidly spreading skin cancer. Which homeostatic imbalance is most likely occurring at the cellular level?

Accepted Answer

Epithelial cells are not contained by the basement membrane and invade underlying tissues.

Question 3

Which type of epithelial tissue is best suited for rapid diffusion and where is it commonly found?

Accepted Answer

Simple squamous epithelium; found in kidney and lungs

Question 4

Which specialized structure on the apical surface of some epithelial cells increases surface area for absorption?

Accepted Answer

Microvilli

Question 5

A gland that releases its product by exocytosis without damaging the cell is classified as which type?

Accepted Answer

Merocrine

Question 6

Which formula correctly represents the process of diffusion that occurs across simple squamous epithelium?

Accepted Answer

$$D = \frac{(C_1$ - C_2$) \cdot A \cdot P}{d}$$

Question 7

Which of the following best describes the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones into the blood; exocrine glands secrete products into ducts.

Question 8

Which type of epithelial tissue lines the bladder and is capable of stretching to accommodate fluctuating volumes of urine?

Accepted Answer

Transitional epithelium

Question 9

A multicellular exocrine gland with a branched duct and sac-like secretory units is classified as:

Accepted Answer

Compound alveolar gland

Question 10

Which of the following is a function of epithelial tissue?

Accepted Answer

Absorption

Question 11

Which type of cell junction is primarily responsible for preventing substances from passing between epithelial cells?

Accepted Answer

Tight junctions

Question 12

Which of the following statements about stratified squamous epithelium is TRUE?

Accepted Answer

It is found in areas subject to high wear and tear, such as the skin.

Question 13

Which of the following best describes the role of the basement membrane in epithelial tissue?

Accepted Answer

It reinforces the epithelial sheet and resists stretching and tearing.

Question 14

A researcher is preparing a tissue sample for electron microscopy. Which step is unique to this method compared to light microscopy?

Accepted Answer

Staining with heavy metal coatings

Question 15

Which type of epithelial tissue is most likely to contain mucus-secreting goblet cells and cilia for moving mucus?

Accepted Answer

Pseudostratified columnar epithelium

Question 16

Which equation best represents the relationship between the rate of epithelial cell regeneration ($$R$$), nutrient availability ($$N$$), and cell division rate ($$D$$)?

Accepted Answer

$$R = N 	imes D$$

Question 17

Which of the following is a correct pairing of epithelial tissue type and its primary function?

Accepted Answer

Simple cuboidal epithelium – secretion and absorption

Question 18

Which of the following is a plausible consequence if the reticular lamina is damaged in epithelial tissue?

Accepted Answer

The epithelial sheet may lose structural support and become more susceptible to tearing.

Question 19

Which of the following is TRUE regarding multicellular exocrine glands?

Accepted Answer

They are composed of a duct and a secretory unit.

Question 20

Which of the following best explains why epithelial tissue must be nourished by diffusion from underlying connective tissue?

Accepted Answer

Epithelial tissue is avascular and lacks its own blood supply.
